Presentation Transcript

  1. Introduction to Bioinformatics: Lecture I An Overview of the Course Jarek Meller Division of Biomedical Informatics, Children’s Hospital Research Foundation & Department of Biomedical Engineering, UC JM - http://folding.chmcc.org

  2. Outline of the outline lecture • Bioinformatics as hypothesis generator for biomedical research in the postgenomic era • Bioinformatics at the University of Cincinnati& Children’s Hospital Research Foundation: research and resources • Introduction to Bioinformatics course: problems and case studies, web and Protein Modeling Lab resources, syllabus and some practical issues JM - http://folding.chmcc.org

  3. Bioinformatics as hypotheses generator 0111010010110001101 Making sense of massive amounts of genomic, proteomic etc. information in order to facilitate further experiments by data mining and inference, modeling and computer simulations. JM - http://folding.chmcc.org

  4. Some more “precise” definitions • “Roughly, bioinformatics describes any use of computers to handle biological information” • “In practice the definition used by most people is narrower; bioinformatics to them is a synonym for "computational molecular biology“ -- the use of computers to characterize the molecular components of living things.” • “The mathematical, statistical and computing methods that aim to solve biological problems using DNA and amino acid sequences and related information.” • More: http://bioinfomatics.org JM - http://folding.chmcc.org

  5. Other “definitions” • Subject or body of research – e.g. google bioinformatics and simply digest the 2 ML (1 ML= 106 Links) or so … • Methods and approaches: computational paradigm in molecular biology and biomedical research • Institutional boundaries – take a body of research from all the scientific institutions having “bioinformatics” in their name • Let us have look at local bioinformatics resources JM - http://folding.chmcc.org

  6. Bioinformatics at the UC and CHRF: Research and Resources JM - http://folding.chmcc.org
